class aws_cdk.aws_cloudfront.Behavior(*, allowed_methods=None, cached_methods=None, compress=None, default_ttl=None, forwarded_values=None, is_default_behavior=None, lambda_function_associations=None, max_ttl=None, min_ttl=None, path_pattern=None, trusted_signers=None)¶

Bases: object

A CloudFront behavior wrapper.

Parameters

allowed_methods (Optional[CloudFrontAllowedMethods]) – The method this CloudFront distribution responds do. Default: GET_HEAD
cached_methods (Optional[CloudFrontAllowedCachedMethods]) – Which methods are cached by CloudFront by default. Default: GET_HEAD
compress (Optional[bool]) – If CloudFront should automatically compress some content types. Default: true
default_ttl (Optional[Duration]) – The default amount of time CloudFront will cache an object. This value applies only when your custom origin does not add HTTP headers, such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. Default: 86400 (1 day)
forwarded_values (Optional[ForwardedValuesProperty]) – The values CloudFront will forward to the origin when making a request. Default: none (no cookies - no headers)
is_default_behavior (Optional[bool]) – If this behavior is the default behavior for the distribution. You must specify exactly one default distribution per CloudFront distribution. The default behavior is allowed to omit the “path” property.
lambda_function_associations (Optional[List[LambdaFunctionAssociation]]) – Declares associated lambda@edge functions for this distribution behaviour. Default: No lambda function associated
max_ttl (Optional[Duration]) – The max amount of time you want objects to stay in the cache before CloudFront queries your origin. Default: Duration.seconds(31536000) (one year)
min_ttl (Optional[Duration]) – The minimum amount of time that you want objects to stay in the cache before CloudFront queries your origin.
path_pattern (Optional[str]) – The path this behavior responds to. Required for all non-default behaviors. (The default behavior implicitly has “*” as the path pattern. )
trusted_signers (Optional[List[str]]) – Trusted signers is how CloudFront allows you to serve private content. The signers are the account IDs that are allowed to sign cookies/presigned URLs for this distribution. If you pass a non empty value, all requests for this behavior must be signed (no public access will be allowed)

Attributes

allowed_methods¶

The method this CloudFront distribution responds do.

Default: GET_HEAD
Return type: Optional[CloudFrontAllowedMethods]

cached_methods¶

Which methods are cached by CloudFront by default.

Default: GET_HEAD
Return type: Optional[CloudFrontAllowedCachedMethods]

compress¶

If CloudFront should automatically compress some content types.

Default: true
Return type: Optional[bool]

default_ttl¶

The default amount of time CloudFront will cache an object.

This value applies only when your custom origin does not add HTTP headers, such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects.

Default: 86400 (1 day)
Return type: Optional[Duration]

forwarded_values¶

The values CloudFront will forward to the origin when making a request.

Default: none (no cookies - no headers)
Return type: Optional[ForwardedValuesProperty]

is_default_behavior¶

If this behavior is the default behavior for the distribution.

You must specify exactly one default distribution per CloudFront distribution. The default behavior is allowed to omit the “path” property.

Return type: Optional[bool]

lambda_function_associations¶

Declares associated lambda@edge functions for this distribution behaviour.

Default: No lambda function associated
Return type: Optional[List[LambdaFunctionAssociation]]

max_ttl¶

The max amount of time you want objects to stay in the cache before CloudFront queries your origin.

Default: Duration.seconds(31536000) (one year)
Return type: Optional[Duration]

min_ttl¶

The minimum amount of time that you want objects to stay in the cache before CloudFront queries your origin.

Return type: Optional[Duration]

path_pattern¶

The path this behavior responds to.

Required for all non-default behaviors. (The default behavior implicitly has “*” as the path pattern. )

Return type: Optional[str]

trusted_signers¶

Trusted signers is how CloudFront allows you to serve private content.

The signers are the account IDs that are allowed to sign cookies/presigned URLs for this distribution.

If you pass a non empty value, all requests for this behavior must be signed (no public access will be allowed)

Return type: Optional[List[str]]
